Radar / Fire Emblem

Since Fire Emblem has been around for more than 20 years, the script writers have managed to slip sexual innuendos in the dialogue more than once. The absolute winner is Fire Emblem Awakening, which has more innuendo than all the other games combined, but Fire Emblem Fates gave it a run for its money and, while not as innuendo-happy, Fire Emblem Heroes and Fire Emblem Echoes: Shadows Of Valentia have also managed to keep up.
